This realizes a programmed operation of continuous bean curd sheet picking, slurry dripping, transfer, and packaging from the pot, with high efficiency. In particular, the bean curd sheet lifting device, through the bean curd sheet peeling frame and the peeling blade structure set on the peeling frame, can automatically extend into the pot to separate the bean curd sheets from the pot body, so as to reduce the tearing and damage of the bean curd sheets during subsequent clamping and improve the quality of the finished bean curd sheet.

Description

Technical Field

[0001] This invention relates to the field of bean curd skin processing technology, specifically to a bean curd skin production line. Background Technology

[0002] Currently, the production of bean curd sheets is still mostly done manually. This involves adding a bean curd-water mixture to a pot, boiling it, and then letting it stand. The mixture on the surface cools quickly and forms a thin film – this is the bean curd sheet. These are then manually removed and hung to dry. However, because the bean curd sheets are laid flat on the surface of the liquid and adhere to the pot's inner wall, manual removal can easily lead to breakage due to improper handling. This results in sheets that do not meet quality requirements, making quality control difficult and yielding a low production rate. Slow removal is time-consuming and labor-intensive, making manual bean curd sheet removal inefficient and labor-intensive. Furthermore, patent application number 202310488440.5 discloses a streamlined bean curd sheet retrieval and shaping device, including a closed-loop conveyor. The present invention comprises a soy milk heating tank, an automatic soy milk replenishment component, and a circulating scooping mechanism. The circulating scooping mechanism includes a frame and a closed-loop conveyor. Drive wheels are located at both ends of the frame, with one drive wheel connected to a drive device. The closed-loop conveyor is positioned between the two drive wheels, and multiple telescopic scooping components are evenly spaced on its outer surface. Each telescopic scooping component has a scooping rod insertion hole at its lower end, aligned with the sealing plug in the soy milk heating tank. The frame is equipped with a first telescopic drive component that acts on the telescopic scooping components to achieve their vertical movement. However, this method directly scoops the soy milk by inserting the scooping rod into the sealing plug on the bottom side wall of the heating tank. This method has significant limitations, and the soy skin is prone to sticking to the inside of the heating tank, causing tearing and damage. Therefore, a soy skin production line is urgently needed to solve these problems. Summary of the Invention

[0038] The embodiments of the present invention will now be described with reference to the accompanying drawings. The terminology used in the embodiments section is for illustrative purposes only and is not intended to limit the scope of the invention. The embodiments of this application will now be described with reference to the accompanying drawings.

[0039] Example: A bean curd sheet production line includes a bean curd sheet lifting device, a transfer device, and a bean curd sheet storage device. The bean curd sheet lifting device clamps and lifts the bean curd sheet in the pot to a certain height. The transfer device transfers the lifted bean curd sheet, and during the transfer process, dripping slurry can be performed to remove excess slurry from the bean curd sheet. Then, the bean curd sheet is transferred to the bean curd sheet storage device for quantitative storage, so as to facilitate subsequent transfer processing.

[0040] In one specific embodiment, with Figures 1-2 For example, from left to right, there are bean curd skin lifting device, transfer device and skin storage device, among which, the skin peeling frame 1 of the bean curd skin lifting device is located at the very beginning of the production line;

[0041] For peeler frame 1, refer to Figure 3 As shown, the peeling frame 1 is equipped with several peeler blades 3, which together form a closed loop that is adapted to the inner wall of the pot. Each peeler blade 3 is equipped with a first driving component that drives the corresponding peeler blade 3 to vibrate. The peeler blade 3 includes a frame 2 and several sets of peeler blades 3, each independently mounted on the frame 2. The first driving component includes a first slide rail 4 and a first slider 5 adapted to the first slide rail 4. Each set of peeler blades 3 is connected to the frame 2. The first slide rail 4 is connected to the frame 2, and the first slider 5 is connected to the peeler blades 3. The first slider 5 moves along the first slide rail 4, synchronously driving the corresponding peeler blades 3 to move.

[0042] Among them, reference Figure 1 , Figure 3As shown, a probe 6 is also installed on the peeling frame 1. The probe 6 is initially flush with the peeler 3, and a first driving member is also arranged between the probe 6 and the peeling frame 1. The first driving member is used to drive the probe 6 to move toward or away from the inside of the pot.

[0043] During operation, the peeling frame 1 moves, controlling the blade 3 to insert from the inner wall of the pot under the bean skin. Then, the first drive unit is activated. The first slide rail 4 is set parallel to the liquid surface. The first slider 5 moves within the first slide rail 4, synchronously driving the corresponding blade 3 to move. Through the reciprocating movement of the first slider 5, the blade 3 vibrates, thereby separating the bean skin from the pot. The probe 6 moves synchronously with the peeling frame 1 to the liquid surface. Then, the corresponding first drive unit drives the probe 6 to move towards the bottom of the pot until it contacts the bottom, thereby measuring the depth of the liquid in the pot and realizing the depth measurement operation.

[0044] A leather clamping frame 7 is installed at the rear of the leather-picking frame 1. Multiple sets of clamping blocks 8 are mounted on the clamping frame 7. Each set of clamping blocks 8 is equipped with a pair of mutually perpendicular track structures. These mutually perpendicular track structures are used to control the movement of the corresponding clamping blocks 8 in the longitudinal and / or lateral directions. (Refer to...) Figure 1 , Figure 4 As shown, multiple sets of clamping blocks 8 are arranged linearly, and each set of clamping blocks 8 has a hollow rectangular structure 12, so as to... Figure 4 For example, a first set of track structures 9 parallel to the liquid surface is installed on the clamping block 8. This first set of track structures is used to control the corresponding clamping block 8 to perform clamping or releasing operations, that is, to control the two blocks of the clamping block 8 to move closer or further away from each other. A second set of track structures 10 is installed vertically on the first set of track structures 9. The second set of track structures 10 is used to drive the clamping block 8 to extend into or away from the pot body. In addition, Figure 4 For example, a third set of track structures 11 is also installed at the top of this set of track structures. The third set of track structures 11 is connected to the second set of track structures 10 on all the clamps 8, and is used to adjust the distance between all the second set of track structures 10 and the clamps 8.

[0045] During operation, the clamping block 8 is extended into the pot and contacts the bean curd skin through the second set of track structure 10. The first set of track structure 9 is activated to control the clamping block 8 to hold the bean curd skin. During this process, since the clamping block 8 is a hollow rectangular structure 12 and has multiple through holes, it can automatically filter out the incoming slurry. Then, the second set of track structure 10 is controlled to drive the clamped bean curd skin to detach from the pot. The control of the third set of track structure 11 can be controlled according to the area of ​​the bean curd skin formed in the pot and the size of the pot.

[0046] For the movement of the peeling frame 1 and the clamping frame 7, refer to... Figure 1As shown, an XY slide structure 13 is installed on one side of the skin clamping frame 7. The skin clamping frame 7 is connected to the XY slide structure 13, and the skin peeling frame 1 is connected to the skin clamping frame 7. The XY slide structure 13 can at least control the skin clamping frame 7 and the skin peeling frame 1 to move synchronously toward the pot body and away from the pot body. With the continuous transmission of the pot body, the skin peeling and skin clamping operations can be performed simultaneously, improving work efficiency.

[0047] The first transfer structure of the transfer device is located behind the clip 7. (Refer to...) Figure 1 , Figure 5 As shown, the first transfer section includes a dripping position, a transfer section, and a temporary storage position. The dripping position is used to suspend bean curd sheets for static dripping. The transfer section is used to transfer the bean curd sheets from the dripping position to the temporary storage position. The dripping position is close to the bean curd sheet clamping frame 7, and a first support frame 14 for receiving the bean curd sheets is provided at the dripping position. A second support frame 15 for receiving the bean curd sheets is provided at the temporary storage position. The transfer section includes a sprocket assembly 16 and a chain 17 mating on the sprocket assembly 16. A bearing block 18 with an opening is installed on the chain 17. The bearing block 18 moves back and forth between the first support frame 14 and the second support frame 15 with the chain 17. The bearing block 18 is configured to support the first bean curd sheet at the first support frame 14. The bean curd sheets are placed on a support frame 14 and then released onto a second support frame 15. That is, the bean curd sheets are lifted and released onto the first support frame 14 by the clamping frame 7. Then, as the sprocket assembly 16 drives the chain 17 to rotate, the carrying block 18 passes over the first support frame 14 from bottom to top and lifts the bean curd sheets on the first support frame 14. As the sprocket assembly 16 continues to rotate, it moves the bean curd sheets to the second support frame 15. At this time, the carrying block 18 is in a reversing position. The carrying block 18 tilts downward and releases the bean curd sheets onto the second support frame 15. The bean curd sheets in the first transfer structure can be dripped, so that the excess liquid on the bean curd sheets falls off.

[0048] The second transfer structure follows the first transfer structure. The second transfer structure includes a rotating gripper configured to hold the bean curd skin at the temporary storage location and transfer it to the bean curd skin storage rack 25 for release. (Reference) Figure 1 , Figure 6 As shown, the rotating gripper includes a gripping end 19 and a rod 20. A rotating shaft 21 is mounted on the rod 20. The rotating shaft 21 is used to control the swing of the rod 20 and the gripping end 19, and to control the gripping end 19 to at least pass through the temporary storage position and the storage rack 25. The gripping end 19 is equipped with a pair of gripping arms 23. A gripping track 22 is mounted on the rod 20. Both gripping arms 23 are slidably mounted on the gripping track 22 and slide along the gripping track 22, controlling the two gripping arms 23 to move closer or further away from each other. The gripping arms 23 have a U-shaped or C-shaped structure, and the two gripping arms 23 are symmetrically arranged with their openings facing each other. A Y-shaped or V-shaped receiving block 24 is provided on one side of the gripping track 22 on the rod 20. The opening of the receiving block 24 is perpendicular to the sliding direction of the gripping arm 23.

[0049] Following the second transfer structure is a storage device, see reference. Figure 1 , Figure 7 As shown, the leather storage device includes a leather storage rack 25, on which at least one crossbar 26 is provided. A second driving member is disposed on the crossbar 26. The second driving member is used to drive the crossbar 26 to swing, and the swing angle is not less than 90°. The second driving member includes a drive shaft 27 and a connecting rod 28 connected to the drive shaft 27. The connecting rod 28 is connected to the crossbar 26 and is rotated by the drive shaft 27, which drives the crossbar 26 to swing. There are three crossbars 26, and two crossbars 26 are arranged in a triangular pyramid.

[0050] refer to Figure 1 , Figure 7 As shown, a retaining plate 29 is installed on both sides of the crossbar 26. A retaining plate cylinder 30 is installed on one side of one retaining plate 29. The retaining plate cylinder 30 controls the corresponding retaining plate 29 to move closer to or away from the crossbar 26. A lever 31 is installed on the other retaining plate 29. The lever 31 is equipped with a power structure 32. The power structure 32 drives the lever 31 to rotate, and through the lever 31, it drives the corresponding retaining plate 29 to move closer to or away from the crossbar 26. The lever 31 drives the corresponding lever 31 to swing at an angle of not less than 90°. The power structure 32 can be a rocker arm structure, that is, a rocker arm is set, and a rotating disk with a power is configured at one end of the rocker arm. By rotating the rotating disk, the rocker arm is controlled to swing, thereby realizing the movement of the lever 31.

[0051] In one specific embodiment, reference is made to Figure 1 , Figure 8 As shown, a scraping structure is provided below the transfer device. The scraping structure includes two sets of scrapers 33, and each set of scrapers 33 includes at least two parallel and staggered scrapers 33. Each scraper 33 is equipped with a first sliding table structure 34. The first sliding table structure 34 controls the corresponding scraper 33 to slide parallel to the direction of movement of the pot body and adjusts the overlapping area between the scrapers 33 in the corresponding set. A second sliding table structure 35 is installed between the two sets of scrapers 33. The second sliding table structure 35 controls the two sets of scrapers 33 to move closer to or further away from each other perpendicular to the direction of movement of the pot body. When the second sliding table structure 35 controls the two sets of scrapers 33, at least all the scraper 33's moving areas cover the inner cavity area of ​​the pot body.

[0052] The scraper 33 is provided with multiple through holes evenly distributed. When the scraper 33 performs scraping operation on the liquid surface, the slurry accumulated in the forward direction of the scraper 33 can be filtered out through the through holes, reducing the amplitude of liquid surface agitation and improving the impurity removal effect on the liquid surface.
